The title compounds, [Co（H2O）6]（OVA）2·2H2O 1, [Ni（H2O）6]（OVA）2·2H2O 2 and [Zn（OVA）2·2H2O] 3 （HOVA = o-vanillic acid = 2-hydroxy-3-methoxybenzoate）, were synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, IR and TGA. Compounds 1 and 2 are both of triclinic with space group P1. The metal atom coordinated by six water molecules displays a slightly distorted octahedral configuration. Interestingly, the carboxyl group from HOVA ligand does not coordinate to the metal atom. Correspondingly, compound 3 belongs to the monoclinic system, space group C2/c. Each zinc（Ⅱ） atom exhibits a distorted four-coordinated tetrahedral geometry. Two monodentate carboxyl groups link one zinc（Ⅱ） atom to form a mononuclear molecule. The structure feature is different from that of compounds 1 and 2, which could be attributed to the different coordinated numbers and radii of Co（Ⅱ）, Ni（Ⅱ） and Zn（Ⅱ） atoms.

A new borate [H2EG][B7O10（OH）3] （1） based on [B14O20（OH）6]4- polyborate anions has been solvothermally synthesized in the presence of H2EG as a template （EG = ethylene glycol）. The structure was determined by single-crystal X-ray diffraction and further characterized by FFIR, elemental analysis and thermogravimetric analysis. Compound 1 crystallizes in the triclinic system, space group Pi, with a = 8.5095（4）, b = 8.8694（4）, c = 10.0756（4） A, a = 95.094（2）, β = 96.936（2）, γ = 116.844（2）°, V = 664.66（5） A3. The structure of 1 consists of [B14O20（OH）6]4- moiety, which could be regarded as the largest isolated polyborate anion so far. The anions are interlinked via hydrogen bonding to form a 3D supramolecular network, whereas the diprotonated [H2EG]2＋ are filled in the free space of inorganic borate network and interact with the inorganic framework by extensive hydrogen bonds. It is noteworthy that the EG acts not only as a solvent, but also as a template.

Reactions of M（Ⅱ） acetate （M = Cu, Ni） with disodium 4,4＇-biphenyldisulfonate （BPDS） and 2,2＇-bipyridine （2,2＇-bipy） yielded three new metal sulfonates formulated as {[Cu2（2,2＇-bipy）2（H2O）（C2O4）（BPDS）]·2H2O}n 1, [Cu（2,2＇-Bipy）（H2O）3]（BPDS）＇2H2O 2 and [Ni（2,2＇-Bipy）（H2O）4]（BPDS）·2.5H2O 3. These three compounds were characterized by elemental analyses, FT-IR spectra, TG-DTA analyses and single-crystal X-ray diffraction analyses. Compound 1 belongs to the monoclinic system, space group P21/c with a = 17.7942（2）, b = 10.1369（10）, c = 19.8681（3） A, β = 104.323（10）°, V = 3472.20（7）A3, Mr = 893.82, Z = 4, F（000） = 1824,μ（CuKa） = 3.295 mm-1, R = 0.0427 and wR = 0.1278. Compound 2 is of orthorhombic system, space group Pca21 with a = 20.1016（7）, b = 7.2460（2）, c = 17.4802（6）A, V= 2546.10（14）A3, Mr = 622.11, Z= 4, F（000） = 1284,μ （CuKα） = 3.314 mm-1, R = 0.0415 and wR = 0.1291. Compound 3 belongs to the monoclinic system, space group C2/c with a = 15.9204（5）, b = 11.7511（4）, c = 15.2559（4）A, β = 98.886（3）°, V = 2819.85（15）A3, Mr = 1288.60, Z = 2, F（000） = 1340,μ（CuKa） = 2.957 mm^-1, R = 0.0515 and wR = 0.1454. Compound 1 is composed of one-dimensional helical chains of [Cu2（2,2＇-bipy）2（H2O）（C2O4）]2＋ fragments bridged alternately by 4,4＇-biphenyldisulfonate ligands, along the c axis of the unit cell. In compound 2, 4,4＇-biphenyldisulfonate anions are arranged in a zigzag mode and interact with the lattice waters via hydrogen bonds resulting in the formation of infinite chains. Adjacent chains are linked by lattice waters to form 2D extended sheets. The complex cations are located in the interlayer regions and interact with the sheets through hydrogen bonds. In compound 3, the Ni center resides at a crystallographic inversion center and adopts a distorted octahedral coordination sphere. The complex cations interact with 4,4＇-biphenyldisulfonate anions via O-H…O hydrogen bonds, creating 2D extended grid structures. The lattice waters are located in the interlayer regions.
